Same brand, different models
Keystone makes 4 ENERGY STAR certified dehumidifiers; this one ranks 3 of 4 for running cost, between the brand's cheapest, the KSTAD224F at $52/yr, and its priciest, the KSTAD506PG at $99/yr.
Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for dehumidifiers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Shopping for a new one
Running above the category average, $99/year is exactly the kind of number that makes a newer, more efficient model pay for itself faster.
Compare current ENERGY STAR certified dehumidifiers before buying.
Protecting what you have
A dehumidifier like the Keystone KSTAD504G is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
Sourcing
Nothing here is estimated from a nameplate wattage; the 525 kWh/yr is ENERGY STAR's own certified figure for this model. Ranked 471 of 546, the Keystone KSTAD504G sits in the middle of the dehumidifier category, see the guide to why your state changes this number for the other half of the math.
